I suspect a water scarecrow might work on herons. Bit easier and less unsightly than netting.
Herons are resident along the local streams here and often to be seen hunting along the one that borders our paddock. In winter we get Great Egrets too so there's an odd territorial clash but generally there's enough space for them all and they like fossicking in the fields as well as the streams.
They don't investigate our pond anymore as it has no fish. Built for drainage and home now to frogs, toads and newts but we have a Wheaten terrier who is a demon huntress and chases anything that moves so herons stay away now. The Lab now gives chase too but they never catch anything.
